I was pleased to discover your site as it aims to give access to the tried and true recipes in MY books. In desperation, I have been building my own spreadsheet of my favourite recipes. I already have over 1,000, and a few of my favourite books are now fully indexed. It's brilliant! :) but I'd prefer someone else to do the work of course :)
I have a couple of problems with your system as it stands though. Firstly searching by ingredients takes just ages. My spreadsheet has a macro in the header line which allows searching on any word(s) which occur in the column - say the ingredients column - and it's much quicker to find all the recipes I have which use those ingredients. Also I can't see how to browse the list of ingredients for a given recipe.
My really big problem is that you only have 2 of my 30 books! It isn't surprising that you didn't start with Australian cookery books, but you don't even have iconic Australians like Charmaine Solomon, Ian Parmenter, Gabriel Gate or Donna Hay. I did find an American edition of Stephanie Alexander's Cooks companion, but it's not my edition, and it seems unindexed as yet.
If this takes off, and I hope it does, could you let me know when you get down to the Antipodes and I'll give it another look?
